Specification of Letters Patent.

Patented Sept. 12, 1911.

Application filed May 27, 1911. Serial No. 629,784.

lb all whom it may concern:

lie it known that 1, JOHN M. Fnonnus, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented new and useful Improvements in Radiators, of which the following is a specification.

In radiators for automobiles as heretofore constructed it has been customary to provide the rear vertical wall of the upper water box or header and the upright water legs on opposite sides of the cellular part of the radiator with a ledge, flange or shelf for supporting the hood of the engine. which shelf was usually separate from this wall and connected therewith by solder. It has alsobeen customary to provide the periphery of the radiator near its rear end or side with an outwardly projecting ornamental bead.

When soldering the hood supporting flange to the rear wall there is great danger of opening the soldered joint between the rear wall and the periphery of the radiator and cause leakage. Furthermore, the engine hood resting upon the supporting ledge or iange is liable to wear the adjacent part of the rear wall of the radiator, owing to the constant vibration of the machine, thereby causing leakage.

It is the object of this invention to provide a radiator in which the hood supporting shelf and the ornamental peripheral bead are both formed integrally with the walls of the radiator and interlocked with each other in such manner that a perfectly tight joint is produced between the rear wall and the peripheral wall and any wear which is produced by the movement of the engine hood relatively to the radiator will be unable to produce openings in the radiator through which water can escape.

In the accompanying drawings consisting of sheets: Figuri l is a fragmentary-vertical longitudinal section of the upper part of an aut mobile radiator embodying my Fig. 2 is a vertical transverse section, on. a reduced scale, in line 22, Fig. 1. Figs. and 4: are fragmentary perspec tive views showing forms of radiators embodying my invention which differ slightly from that shown in Figs. 1 and 2.

Similar numerals of reference indicate corresponding parts throughout the several views.

In its general organization the radiator shown in the drawings for illustrating the application of my invention comprises a cel lular body 1 forming external horizontal air passages and vertical internal water channels or passages, an upper header or water box 2 connected with the upper ends of the water channels or spaces of the cellular body, and two water legs 3, 3 arranged vertically on opposite sides of the cellular body and connecting opposite ends of the upper header with the lower header or water box of the radiator which is not shown in the drawings but which is of the usual construction.

4t represents the vertical or upright front wall of the upper water box and the water legs, 5 thevertical or upright rear wall of the same and G the peripheral outer wall which is connected with the outer edges of the front and rear vertical walls.

The front edge of the peripheral wall may be connected with the outer edgeof the front wall in any suitable manner but preferablyby providing the outer edge of the front -wall with a forwardly projecting flange 7 which is secured within an in- 'ardly turned channel 8 formed 011 the front edge of the peripheral wall by means of solde The rear edge of the peripheral wall and the outer edge of the rear wall may be connected with each other in various ways in accordance with my invention. In the form shown in Fig. 1 the outer edge of the rear wall is provided with a laterally and rear wardly projecting bead 9 formed integrally therewith and of substantially semi-circular form and the rear edge of the peripheral wall is provided with a corresponding laterally and rearwardly projecting bead 10 formed integrally therewith and fitting over the outer side of the bead of the rear w. ll. These two beads may be connected-with each other in any suitable manner so as to form a water tight joint between the same but preferably by soldering this joint.

The rear edge of the bead of the rear wall is provided with a rearwardly projecting flange 11 formed integrally therewith and constituting a shelf or ledge-upon which the front edge of the hood 12 is supported which covers the space in which the engine and associated parts of the automobile are arranged. The outer side of this supporting hood, due to vibration of the machine, should wear the beads of the peripheral and vertical rear wall of the radiator to aconsiderable extent, such wear Wlll not 1mpa1r the efficiency of the radiator inasmuch as the walls of the radiator are still intact and no leak age can therefore occur as would be the case if the radiator hood were supported in engagement with the rear wall of the radiator and thus constantly tend to wear the same. Furthermore, the integral formation of the hood supporting flange with therear wall.

of the radiator dispenses withtheseparate solder oint which has been employed here tofore for connect ng this flange with the radiator in addition to 'thesolder joint which connected the rear wall and peripheral wall, thereby; avoiding the liability of loosening up the [joint between the radiator walls and preventing leakage while attaching the hood supporting flange th the radiator.

By fori'ning' the heads integrally on the.

rear and peripheral walls of the radiator and interlocking the Stlll'iG in th they also per arate head a iich has heretofore been secured to t ea'adiator :t'or m-nan'iental purposes. 7 i

i l Instead of lornnng the hood supporting flange .on lihe rear edge of the head of the realflwal'l'ol the radiator this flange may he formed'o'n the rear edge o'lithe head 01 the peripheral wall as shown atl lin Fig. 3.

The head hi the rear \\'all-"insl.e:ul oit' pro- "ianner described these paits are not onlyheli] 1n ll'Q reliably 111 place relatively to each other but" t ot dis 'iensing with a sep-v je cting laterally and rearwardly from the same, as shown in Fig. 1, may also project forwardly and laterally therefrom in the form of a loop, as shown at 15 in Fig. 4.

In all of the several constructions described the rear and peripheral walls of the radiator are provided respectively with integral beads which interlock with each other and one of these beads is provided with a supporting flange upon which the engine hood is supported in such manner that the wear'of this lrood is taken up by the beads and the adjacent wall of theradiator is saved. from such. wear so that leakage does not occur.

I claim as my invention:

l. radiator having a vertical wall provided at its edge with a bead. and. a. peripheral wall provided with a head which engages with the head of the vertical wall, one of said beads being prov ded with a vflange for supporting an engine hood.

2. A radiator having a vertical rear wall provided at its edge with a laterally to jecting bead and a peripheral wall provided 'at its rear edge with a laterally 'n'ojccting head which engages with the outer side of the bead on sa idrear wall, one of said beads v having a rearwardly pro ecting flange wlnch is :lapted to support". an engine hood.

3. A radiator having a vertical rear wall provided at its edge with a head which pro jects laterally and rearwardly from said rear wall and is provided at its rear edge with a rearwardly projecting flange adapted to support an engine hood, and a peripheral wall provided at its rear edge with a head which projects laterally and rearwardly and which is secured over the head of said rear wall.

Witness my hand this 25th day of hIay, 1911.
